Mstest - does not load the test dll if UNC path is referenced in the testcontainer

Question

When I ran a automated test from the MS Test Manager, it failed with the below message.

"Error adding test case [123] to test run: Could not load file or assembly 'file://\localhost\TFS\OGUI\OGUI_20111228.8\catsprojects.dll' or one of its dependencies. The system cannot find the file specified."

Also when I ran the recorded test using MsTest with local reference, the dll loaded and the playback was done.and the test ran successfuly.

eg.  mstest /testcontainer:D:\TFS\OGUI\OGUI_20111228.8\CATSProjects.dll

But with UNC Path, the dll was not loaded and it showed the below error.

mstest /testcontainer:"\200411dc0310\TFS\OGUI\OGUI_20111228.8\CATSProjects.dll"

Could not load file or assembly 'file://\200411dc0310\TFS\OGUI\OGUI_20111228.8\CATSProjects.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

How do we fix this and run the tests referencing the UNC path?  

Any help is greatly appreciated.

Thanks

Hi

When I ran a automated test from the MS Test Manager, it failed with the below message.

"Error adding test case [123] to test run: Could not load file or assembly 'file://\localhost\TFS\OGUI\OGUI_20111228.8\catsprojects.dll' or one of its dependencies. The system cannot find the file specified."

Also when I ran the recorded test using MsTest it failed 

mstest /testcontainer:\200411dc0310\TFS\OGUI\OGUI_20111228.8\CATSProjects.dll

Could not load file or assembly 'file://\200411dc0310\TFS\OGUI\OGUI_20111228.8\CATSProjects.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)

MSTest loaded the dll and played back only if the dll location is referenced with the "local path" instead of "shared path."  

mstest /testcontainer:D:\TFS\OGUI\OGUI_20111228.8\CATSProjects.dll

But with UNC Path, the dll was not loaded and it showed the above error. 

How do we fix this in both MTM and MStest? Please help.

Thanks

Hi, you could use the xcopy command to copy the files before running the tests http://www.computerhope.com/xcopyhlp.htm

Answer 3

That will work with MSTest but how to fix in MTM where we associate the test plan with a Build (output of which is stored in UNC Path).

Whether MStest supports dll referenced in a share folder ?

Answer 4

Hi, for the MTM scenario, the test agent copies the files locally from the build drop into %localappdata%\VSEQTand it works well.

Hi Mush,

I am moving your thread into the Testing with Visual Studio Test Manager (MTM) Forum for dedicated support. Thanks for your understanding.

Have a nice day,

Hi,

UNC path wont work. You can copy the dll locally using xcopy command and then run the tests using mstest command.
